Definitions

  • the present invention relates to an atomizer designed for a very fine atomization, in the shape of aerosol of products either dissolved or mixed in a gas liquefied under pressure and particularly of insect-killers, of up-keep, painting, varnishing products or of similar products soluble in a liquefied gas.
  • the apparatus of this kind generally designated as bombs, consist of a container provided with a valve which is usually of the type used for the motorcar tyres, the body of which is provided with a restricted discharge outlet and with a push button to control the opening of the valve.
  • Such valves are nevertheless very expensive and offer for this use many drawbacks, the most important being that it is very difiicult to secure their tightness.
  • the apparatus, object of the present invention copes with these drawbacks and it is characterized in that the container of the liquefied gas is provided with a valve engaging a seat surrounding an opening in a wall of the container and which is carried by a valve stem fixed at its other end to another wall of the container, one of these walls being flexible and resilient, thus allowing, on the one hand, the opening of the valve through a controlled deflection of the wall and, on the other hand, the application of the valve on its seat under the action of the gas pressure in the container.
  • the Figure 1 shows in vertical axial section a first embodiment of the apparatus, including a flexible bottom.
  • the Figure 2 illustrates in perspective the control wrench.
  • the Figure 3 illustrates in vertical axial section an alternative form of the above apparatus.
  • the Figure 4 illustrates in vertical axial section an alternative embodiment, in which the apparatus has a flexible lid.
  • the Figure 5 illustrates a third embodiment of the invention in which the two walls, flexible and rigid, between which is mounted the stem of the valve are located in the upper portion of the container.
  • FIGS. 6 and 7 illustrate respectively, in axial and cross sections, another form of embodiment in which the valve is set on a removable plug.
  • the Figure 8 is an alternate form of the preceding plug.
  • the apparatus illustrated in Figure 1 includes a container for the liquefied gas wherein the product to be atomized is dissolved.
  • This container comprises a cylindrical body 1, a resilient flexible bottom 2, in the shape of a cup with a flat bottom and a set lid including a conical portion 3 and a cylindrical portion 4.
  • a piece 6 is
  • the part of the valve body 6 situated outside the container has a cylindrical chamber 7 having a central boring 8 which extends through the cylindrical portion 9 of the body 6 inside the container and on which is fitted a pipe 10 opening close to the bottom 2 of the container 1.
  • the valve body 6 is provided with a screwed plug 11, in which is bored the atomization nozzle 12.
  • the bottom of the cylindrical chamber 7 forms the seat for a valve 13, provided with a tight joint 14 and carried by a stem 15, the lower end of which is screwed in a piece in the shape of a nut, 16, set in the centre of the resilient bottom 2.
  • a control wrench is foreseen in the apparatus (Figs. 1 and 2). It consists of a small plate 17 with two hooks 18, 18' engaging the setting flange 19 of the bottom 2 on the body 1 and of a bore 20 to receive the head 21 of the nut 16 set in the bottom 2.
  • the plate 17 extends in a handle 22, bent upwards: when the handle 22 is applied against the body of the container (in the direction of the arrow), the required defiection of the bottom 2 is produced and the valve 13 is lifted.
  • the apparatus according to the invention is simple, strong, and possesses a perfect and lasting tightness as the force exerted by the compressed gas upon the valve 13 through the bottom 2 and the stem 15 and maintaining said valve on its seat is very important.
  • the apparatus can be used several times: once the apparatus is empty, the plug 11 and the valve 13 are unscrewed, the product to be urged in solution is introduced in the container through the central pipe 10, the valve 13 is anew placed in position and the container is filled with the liquefied gas, the valve being kept open for this purpose.
  • valve stem 15 and the central pipe 10 are combined in a single member: the valve 13 is therefore fixed at the upper end of a tubular stem 23, the lower end of which is screwed in the bottom of the container 1.
  • the tube 23 is provided, close to the bottom 2, with an aperture 24 connecting it with the inside of the container 1 and, in the immediate vicinity of the valve 13, with an aperture 25 through which the gas expands in the chamber 7.
  • the tube 23 enters the container 1 through a tight joint, for instance a junk packing, formed by a ferrule 26 mounted on the lower end 9 of the valve body 6 and containing a compressed felt 27.
  • the Figure 4 illustrates an embodiment of the atomizer which is suitable when the internal pressure in the container 1 is comparatively small, thus allowing to control directly the valve with the hand, without a wrench.
  • the lid of the apparatus includes, on
  • a resiliently flexible membrane 28 made of a' plastic material or a thin metal, in the centre of which is set a tubular piece 29 forming the body of the valve provided with a valve seat 30, a lateral atomizing nozzle 31 and arplug 32 which .used Mé time-as a "control push button.
  • a rigid metallic sheltering lid 33 covers on the other hand the flexible membrane, except in its centre part.
  • the valve 13 isimounted as above described, for instance according to the embodiment of Fig. l, on a solid stem 15, screwedin the bottom 2 and surrounded by the pipe 10.
  • the push button 32 When operating the apparatus, the push button 32 is depressed whereby the flexible membrane 28 is lowered together with the valve body 29 and valve .seat 30 resulting in that, as shown in .Fig. 4, the valve 13 disengages the seat .30 allowing .the gastoescape from the container into the valve body .29 and to be discharged therefrom through the restricted outlet 31.
  • Fig. 4 could also be made with arigid lid and a flexible bottom.
  • the container which is to receive a product dissolved in the liquefied gas includes an upper frusto conical part 31, set of the cylindrical body 32 and ending in a flat lid 33 which i can be deflected by means of a wrench 34 which engages the flange of the lid 33 by means of three books 35, 35', 35" and imparts to the lid, through a teat v36, the pressure applied to the hand-grip 36', thus producing a slight resilient deflection of the centrepartof the lid.
  • An aperture 37 is provided in the central part of the lid.
  • This aperture is fitted with a joint preferably made of a plastic material, in the shape of a flange 38 .and forming a seat for a valve constituted by the head 39 of a screw, the stem 40 of which is screwed with a tight fit in a small rigid plate 41 soldered inside the part 31 of the container, at some distance under the lid 32.
  • This small plate 41 has an aperture 42 connecting the valve 38-459 with the inside of the container and .in which is set the end of a tube 43. .A cap 44, provided with a small aperture 45, acting as an atomization nozzle, is fixed, either by soldering or in a removable Way, to the lid of the container above the valve.
  • a return spiral spring 45 is arranged around the stem 40 of the valve between the rigid plate 41 andthe distortable lid 33.
  • the device operates as .follows:
  • the stress applied .on the wrench 36 produces, through the resilient deflection of the lid 33, -a lowering of the seat 38 and thereby the opening of the valve; the gas can expand out .of the container, carrying along the product dissolved therein.
  • the wrench 36 is released, the gas pressure and also the return spring 46 will bring the lid to its initial position, securinga tight closing of the valve.
  • the Figures 6 to Z8 relate .to .a form of-embodiment of the invention allowing an atomization valve of the above described type to be provided on a glass flask, particularly intended to spray perfumes, Cologne water and other perfumery products which are usually contained in glass flasks, without altering the outside appearance of these products.
  • valve is set in a hollow plug having a rigid bottomin thecentre of which is fixed, in a-tapped opening, thethreaded valve .stemprovided with a grooved orflattened face for the outflow of the gas, whilst the seat of the valve is arranged in the centre of anintermediate flexible partition which is tightened against the upper flange of the hollow plug by an also flexible fastening, set on said flange,
  • Figs. 6, .7 comprises a plug made of metal or of plastic material, comprising a cylindrical threaded part 51 to be screwed on the flask (not shown) and an upper part 52, having the shape of a cup or dish with a rigid bottom 53 having in its middle part a tapped pipe 54 upon which, on the one hand the plunger 55 of the atomizer is firmly fixed and on the other hand the threaded stem 56 of the valve 57 is screwed, this stem being provided with a flattened face 58 to permit the escape through the pipe 54 of the gas carrying the product to be atomized.
  • The'valve 57 rests on a seat constituted by a fluid-tight packing 59 fixed in'the middle of a flexible wall 60 which closes the upper part 52 of the plug and is kept into position by an also flexible fastening set of the part 52 of the plug and made integral with the wall 60 by means of a perforated tubular flange 62 surrounding the valve 57.
  • An atomization nozzle 63 is drilled in the fastening 61, .for instance .in the vicinity of the-periphery of the plug.
  • the threaded -,part 51 of the plug has been suppressed and the hollow body, 52, in the shape of a cup, is disposed by means of a fluid-tight packing 64 upon the upper edge of the flask having a circular boss 66, whilst a metallic belt hearing upon the atomizing-plug with the upper edge bent inwardly, allows the plug to be set on the bottle like acap, .byihooking the lower edge of the belt 65 under the boss 66, as shown in dotted lines.
  • the apparatus functions exactly like the apparatus of Figs. ,6 and 7.
  • An atomizing apparatus for storing and dispensing products dissolved in or mixed with a liquefied gas revtained under pressure, comprising a container having a peripheral wall and top and bottom end walls, said top wall having an aperture therein, a valve body fitting in said opening with a gas-tight connection and comprising a valve chamber provided with a restricted discharge outlet opening outside the containers and a .bore extend ing from said chamberto the inside of the container, a valve seat :in said chamber around said bore, a tubular valvestem having its lower end fixed to the bottom end wall of the container and extending up through said bore, :a valve on the upperend of said stem inside said chamber and engageable with said seat, means providing .a fluid tight seal between said stem and said bore of the valve body, said tubular stem being longitudinally slidable through said fluid tight seal and having an aperture in its lower-portion opening into the interior of said containeranda second aperture in its upper portion opening into said bore of the valve body above said fluidtight seal but below the valve seat to connect the
